Addiction, misuse, and abuse may lead to overdose and death. Assess risk before prescribing and regularly monitor for signs of these behaviors and conditions. Serious and potentially fatal respiratory depression may occur. Monitor for respiratory depression, particularly when initiating or increasing dosage. Prolonged use of oxymorphone injection during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated. If opioid use is required for a prolonged period in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available. Concomitant use of benzodiazepines or other CNS depressants, including alcohol, and opioids may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing for patients with inadequate alternative treatment options. Limit dosages and durations to the minimum required and follow patients for signs and symptoms of respiratory depression and sedation .

Uses for Numorphan
Oxymorphone injection is used to treat moderate to severe pain, including labor pain. It may also be given before surgery or with a general anesthetic (medicine that puts you to sleep), and may be used to relieve anxiety for patients with breathing problems from pulmonary edema caused by heart disease.
Oxymorphone belongs to the group of medicines called narcotic analgesics (pain medicines). It acts on the central nervous system (CNS) to relieve pain.
When oxymorphone is used for a long time, it may become habit-forming, causing mental or physical dependence. However, people who have continuing pain should not let the fear of dependence keep them from using narcotics to relieve their pain. Mental dependence (addiction) is not likely to occur when narcotics are used for this purpose. Physical dependence may lead to withdrawal side effects if treatment is stopped suddenly. However, severe withdrawal side effects can usually be prevented by gradually reducing the dose over a period of time before treatment is stopped completely.
This medicine is available only with your doctor's prescription.
